In-situ generation of poly(quinolizine)s via catalyst-free polyannulations of activated diyne and pyridines
文献摘要：
The development of new polymerization routes to afford N-heterocyclic polymers is of vital importance and highly desired for various practical applications.Herein,a facile and efficient polyannulation reaction of dual-activated alkyne and pyridines was developed to construct novel N-heterocyclic poly(quinolizine)s.This polymerization can proceed smoothly under catalyst-free conditions with 100％atom utilization to furnish poly(quinolizine)s with high molecular weights(up to 34,100)and well-defined structures in acceptable yields.The resulting polymers show good solubility,high thermal stability and strong red emission.Moreover,the prepared poly(quinolizine)s exhibit low cytotoxicity and can selectively label lysosomes in live cells.Considering the remarkable advantages of readily available raw materials,mild polymerization conditions,atom economy,and excellent product performance,this new and efficient polymerization tool will open up enormous opportunities for preparing functional N-heterocyclic polymers.
